Hey #Cars folks: I'm getting mixed info on this with some being hearsay and its hard to sort:

I have a 2015 Toyota Corolla LE, CVT, at 119000 miles on it. I'd heard I need to replace the CVT fluid because "lifetime" means "expected life of the car", 250k miles.

What's mixed is amount, and when it is/isn't safe to anymore. I'm hopeful that I've not waited too long for it to be safe because of CVT nonsense, and confused on amounts/regularity to maintain it for a good while.
